Only downfall is he trusts Mascherano alot and will probably be really reluctant to bench him no matter what since they are countrymen.
I highly doubt Tata is that retarded to give Masch priority in the squad just because he's Argentine... Do you have any idea how many problems that would cause in the dressing room?
Anyway, Tata looks like a sensible coach. He seems very determined and focused in his tactics, very much like Pep. I actually enjoy the change of play he does to make the team as flexible as possible.
One big thing I noticed this season is there are clear instructions from the coaching staff to pass long balls and take more risks with passes. During Tito era and even the last year of Pep, we often saw Iniesta, Xavi and Busquets just doing everything they can to keep the ball, which resulted in sideways passing. This is not that great of a tactic and is way too predictable for opponents.
Whoever gave that really long lobbed pass to Neymar deserves lots of praise from me! Was an excellent chance for Neymar since the pass was incredible accurate.
